why does a cardinal attack my window

Are Cardinals Or Robins Crashing Into Or Pecking at Your Windows? Throughout the year we receive emails asking,
"What can I do to stop Cardinals and Robins from crashing into or pecking at my windows? " First, you need to know why they do this. Cardinals and Robins are very territorial birds. When birds see another of the same species in its breeding or feeding territory, it instinctively attacks the other bird. Your house or cars windows act as mirrors to the birds. When they are close enough to see their own reflection, they interpret this as an intruder and begin attacking or pecking at the window to chase the intruder away. Each year, thousands of birds including Cardinals and Robins die, crashing or flying into windows.


In this case, the bird sees a refection of trees or sky and is unable to tell that the window is a solid barrier. We as bird watchers need to take every measure possible to remedy this problem. What do I do to stop birds from crashing, pecking windows? Decrease the reflectivity of your windows: Create a physical barrier: Build a net frame to act as a barricade by mounting fine-mesh netting (available at garden centers or hardware stores) in a rigid frame, using shelf brackets to hold the frame a couple of inches away from the window. Install indoor-outdoor blinds on the outside of your windows. Adhesive-backed cut-out silhouettes of hawks or falcons in flight to attach to the outer surfaces of reflective glass are sold in virtually all stores catering to naturalists and birders.


In fact, any shape will work. The non-reflective cutout helps the birds focus on the glass and, knowing it's there, avoid it. If you're a bird watcher and feed birds, consider moving your feeders further away from windows. While these measures won't guarantee Cardinals and Robins will stop pecking and crashing into your windows, they may minimize the behavior. One last point This behavior is at its peak during the nesting season. For the most part, this behavior decrease as soon as the young leave the nest.

The advice given by the RSPB (Royal Society for the Protection of Birds, a British wildlife charity) to prevent birds attacking panes of glass is to cover the outside of targeted windows with non-reflective cellophane. The problem with this is that wind and rain will quickly make the cellophane come adrift and ineffective. Their alternative suggestion is to cover the inside of affected windows with newspaper or lots of decals. Or you could leave curtains and blinds drawn to make the glass non-reflective. However, thereБs a huge disadvantage to these solutions. The birds may stop pecking your window, but you will no longer be able to enjoy looking out through it.


You could use a medium-weight plastic painter's drop cloth instead. The cloudy plastic will allow you to see out and let a reasonable amount of light enter, but will eliminate the birdБs reflections. The idea is to attach the plastic sheet to the top of the outside of your window and leave it to hang loosely. Any movement in the sheet caused by breezes will help to scare away the bird. Bird's Eye View window deflector works well. It breaks up the clear view of the glass for birds and stops them striking at their reflection. At the same time it's small enough not to obstruct your view of the outside. It's also easy to remove from the window if you should want to.
